How much yard can one battery charge cover?

Across the reviewers and Reddit threads in our data, a 4.0Ah 40V battery typically handles roughly 1/3 acre, a 6.0Ah 56V battery covers up to ~55 minutes of run time, and a 7.5Ah 56V or dual-4.0Ah 60V setup pushes toward 60–90 minutes — enough for most 1/2- to 3/4-acre lots in a single session.
